pressure switch
Version with galvanically isolated digital thresholds – TED5
and TEDM
The current supply to the pressure switch is electrically isolated from
the threshold outputs and the threshold outputs are isolated from each
other.400 mA at 60 VDC or 40 VAC.
It is possible to have a separate power supply between the TEDM
(≤ 32 VDC) and the threshold contacts (≤ 60 VDC or ≤ 40 VAC).
Configuration
The three keys on the front panel are used to configure the following
operating parameters:
● Switching point value for each threshold
● Switching hysteresis value for each threshold
● Active status for each threshold (NO or NC)
● Time delay of each threshold from 0 to 25 s in 0.1 s steps
● Auto-zero function
● Self test and parameter protection by a 4 digit code
Additional parameter for the TEDM:
● Modbus slave address of the pressure switch
● Parity selection
Maximum and minimum value consultation
When the pressure switch is in the measurement mode it is possible
to display or initialise the maximum and minimum pressure values
saved at any time.
Modbus communication
The TEDM has a RS485 serial port and uses the Modbus RTU communication protocol.
The Modbus protocol is a two-way exchange protocol based on a
hierarchical data base structure between a master and multiple slave
stations. It enables the user to read the pressure and the status of
each threshold (open or closed).
Exchange between the master and one slave: The master sends an
order and waits for a reply.
Exchange between the master and all slave stations: The master
broadcasts a message to all the slaves in the network and they perform the order in the message without sending a reply.
Two slave stations cannot talk together.
The bus stations are identified by addresses given by the user. These
addresses range from 1 to 247.
Parameter consultation
Parameters for each threshold, Modbus address (TEDM) and parity
(TEDM) can be viewed whithout access code.
