RT-2 RELAY
TERMINAL
PARM-SIZED,
16-CHANNEL
RELAY TERMINALS
FEATURES
• Compact, space-saving design:
The Relay Terminal with 16 I/O channels
measures only (W)116 × (D)52 × (H)37
mm (W)4.57×(D)2.047× (H)1.457 inch.
The compact design contributes to
equipment downsizing.
• Incorporates PA Relays with highsensitivity twin contacts and Au-cladding:
The Relay Terminal incorporates 5 mm
.197 inch wide PA relays. The PA relay
features high sensitivity (12 V type = 120
mW, 24 V type = 180 mW) and twin contacts with Au-cladding, which combine to
ensure high reliability under low-level
loads.
• Available in input and output devices
• Available in Pressure connector connect type and wire-direct connect
type:
Pressure connector connect type has a
single common for four I/O channels.
The Wire-direct connect type has a single common for each I/O channel.
• Incorporates a surge absorber:
The RT-2 Series incorporates a surge
absorber to protect the programmable
controller internal electronics from inductor turn-off surges.
Pressure connector connect type
Wire-direct connect type
• Equipped with LED indicator lights:
LED indicators allow the user to identify
the relay status at a glance.
• Comes with AXM connector (long lever version):
The RT-2 Series comes with the AXM
connector (complying with the MIL standard) for single connections. Cable designed for use with AXM connectors are
also available.
• Ease of mounting on DIN rails:
The DIN rail mounting hook of relay terminal is provided with a release/retention mechanism to ease mounting and
removal.
• Available with a wide variety of cables:
A wide variety of assembled cables offers compatibility with our programmable
controllers, and wire-pressed terminal
cables provide compatibility with other
controllers.

Notes: 1. The value of breakdown voltage and insulation resistance is the initial one.
2. Condensing occurs when the unit relay is exposed to sudden temperature change in a high temperature and high humidity atmosphere. This
may cause some troubles like insulation failure of the socket or the print circuit board. Take care under this condition
3. Below 0°C 32°F, condensing water can freeze and cause socket contact failures and other problems. Take care under this condition.

1. When equipped with Power PhotoMOS relay voltage sensitive type
Since the Power PhotoMOS relay voltage
sensitive type does not require the current-controlling resistance on the input
side, it can be used together with PA relays on 4-point unit relays (PA relay types)
or RT-2 relay terminals.
When connecting Power PhotoMOS relay
voltage sensitive types to 4-point relays
(PA relay types) or RT-2 relay terminals, it
will be necessary to be careful of load currents (since it will be a close connection).
Be sure to use within the range given in
the load currents and ambient temperature characteristics graphs given below.

2. Operating environment
1) Use the product at ambient operating
temperature between 0°C and 55°C 32°F
and 131°F. (When installing in the control
panel, take heat release into due consideration. Installing of the product at 90 degrees to the control panel is
recommended. When installing the product horizontally or placing it on a heating
unit, use a cooking fan.)
2) Keep the supply voltage within the
range of 90% V to 110% V of the rated
voltage.
3) Keep the product as far as possible
from power cables, high tension equipment, power equipment, equipment with
transmitting devices such as amateur radios, or equipment which generates a
large switching surge.
4) The main unit is made of resin; therefore, do not use it in areas where it may
come in contact with (or be exposed to)
organic solvents such as benzine, thinner,
and alcohol or strong alkaline substances
such as ammonia and caustic soda.
5) Do not use the product in areas where
it may be exposed to flammable gases,
corrosive gases, excessive dust, or moisture, or areas where it may be subjected
to strong vibration or shock.
3. Dropping
If a unit is dropped be sure to check its external appearance and characteristics before using it.
4. Installing and removing the module
1) Firmly insert the module into the socket
with the terminals going in the direction of
the blade receptacles.
2) The module can be easily removed using the removal key.
(1) Insert the removal key into the socket
slots.
22
(2) Pull the removal key up to remove the
module.
6. Installation
1) Perform mounting hole cutout according to the panel cutout drawings.
2) When installing the unit on a DIN rail,
use the DIN rail locking lever on the side
of the unit. Installation is accomplished by
simply fitting the unit onto the rail and
pressing gently.
1 First push in
the DIN rail
locking lever.
DIN rail locking lever
DIN rail
5. Wiring and circuit configuration
1) Make all connections according to the
schematic. Polarity should be observed
when wiring DC type.
2) Use of wire-pressed terminal is recommended for connections to pressure connector connect type. For the wire-direct
connect type, strip wire ends to the specified length.
3) When wiring power lines or power cables, twisted pair treatment (standed wire
treatment) should be done in order to improve noise resistance.
4) When the load output device is an inductive load type, installing a diode and
surge absorber to both ends of the load is
recommended.
5) In order to improve noise resistance,
class 3 grounding of the control panel is
recommended.
6) Do not pass the wiring over the surface
of the case. (When unavoidable, keep the
wire at least 3 cm 1.181 inch away from
the surface of the case.)
7) Turn off the power before connecting/
disconnecting connector cables.
8) With some types of control devices,
leakage current may cause the relay to fail
to turn off after the control input is turned
off. Make sure that the relay turns off after
the control input is turned off.
3 Press the unit onto
the DIN rail.
2 Hook the holders on the
unit over the DIN rail.
3) To remove the unit from the DIN rail,
use a flat head screwdriver to pull out the
DIN rail locking lever.
3 Remove the unit from
the DIN rail.
2 Move the
screwdriver in
the direction
of the arrows,
and pull out
the lever.
1 Insert the tip of the
flat head screwdriver
into the slot in the
DIN rail locking lever.
7. Transporting and storage
1) If the product is subjected to extreme
vibration while being transported, the relays may become detached, the lead may
become bent, and the unit may become
damaged. Handle the inner and outer
boxes with care.
2) If the product is stored in an extremely
adverse environment, visible defects and
deterioration of performance characteristics may result. We recommend the following storage conditions.
• Temperature: 5 to 30°C 41 to 86°F
• Humidity: Max. 60% R.H.
• Environment: No hazardous substances such as sulfurous acid gases
and little dust.
