For replacement relays, use relays with the same voltage specifications as the relays provided with the Terminal when it was purchased. Longer operating life can be achieved by replacing the G6B-4@@ND with the G6B-1147P-FD-US. 2. Standard models are also available without relays mounted to the sockets. To obtain such terminals, replace the “G6B” portion of the model number with “P6BF.” For example, to order G6B-4BND with empty sockets, use model number P6BF-4BND. Also specify voltage specifications for models with operation indicators. 202 Terminal Relay G6B-4@@ND Specifications ■ Ratings Coil Ratings (per G6B Relay) Rated voltage 5 VDC 12 VDC 24 VDC Rated current 35.5 mA 19.1 mA 10.7 mA Coil resistance 125 Ω 720 Ω 2,880 Ω Must operate voltage 80% max. of rated voltage Must release voltage 10% min. of rated voltage Max. voltage 130% of rated voltage Power consumption Approx. 200 mW Note: 1.

G6B-4-C Terminal Covers (Two per set) 206 Terminal Relay G6B-4@@ND Precautions Wiring Relays Mounted Be sure to turn OFF the power when wiring the Unit and do not touch the charged terminals of the Unit. Otherwise, an electric shock may result. Do not apply overvoltage to the input terminals. Otherwise, the Unit may malfunction or burn. G6B-4@@ND standard: G6B-1114P-FD-US G6B-4@@ND long life: G6B-1174P-FD G6B-4@@ND high reliability: G6B-1184P-US Replacement is not possible for G6B-48BND. Wiring Relay Models Be sure to connect the input terminals with the correct polarity. Do not connect the Unit to loads exceeding the rated switching power (switching voltage or current). Otherwise, faulty insulation, contact weld, or faulty contact of Relays, or damage to Relays may result, or the Relays may malfunction or burn. The life of Relays varies with the switching condition. Test the Relays under the actual operating conditions before using the Relays within the permissible switching frequency. The use of deteriorated Relays may result in the faulty insulation of the Relays or cause the Relays to burn. Do not use the Unit in locations with inflammable gas. Otherwise, a fire or explosion due to the heat of the Relays or sparks from the Relays may result when they are switched. Coil Voltage Be sure not to impose voltage exceeding the permissible voltage on the coil continuously. Do not use the relays when other inductive loads are connected in parallel with the coil input or when there are surges during power supply because the built-in diodes used to absorb surge may be destroyed. Do Not Use the Following Circuit ■ Correct Use Inductive load Mounting Heat generated by the relays must be considered when gang-mounting. Space must be provided between the relays or other methods must be taken to maintain the relays’ ambient temperature at 55 °C or lower. Replacement of Relays G6B-4@@ND Use the P6B-Y1 Removal Tool as shown in the following diagram. G6B Coil Coil surge current absorption diode Handling Do not drop, shock, or vibrate the Unit excessively. Otherwise, damage to the Unit may result or the Unit may malfunction. Make sure that all the Relays are properly mounted before use. Screw Tightening Torque Tighten each terminal screw to a torque of 0.78 to 1.18N·m. Tighten each mounting screw to a torque of 0.59 to 0.98 N·m. Installation Environment Be sure to turn OFF the power to the Unit before replacing a Relay. Relays must be inserted straight onto the socket connector pins to ensure proper connection. G6B-48BND models (high reliability) are connected directly to boards to increase reliability and the relays are thus not replaceable. If relay replacement is necessary, use the P6BF-4BND Terminal Sockets together with the G6B-1184P Mini Relays. P6BF-4BND Terminal Sockets are equipped with relay replacement sockets. Do not mount Relays that are different to one another in voltage. Do not install the Unit in the following locations. Otherwise, damage to the Unit may result or the Unit may malfunction. Locations with direct sunlight. Locations with an ambient temperature range not within 0°C to 55°C. Locations with rapid temperature changes resulting in condensation or locations with relative humidity ranges not within 10% to 90%. Locations with corrosive or inflammable gas. Locations with excessive dust, salinity, or metal powder. Locations with vibration or shock affecting the Unit. Locations with water, oil, or chemical sprayed on the Unit. Disassembly, Repair, and Modification Do not disassemble, repair, or modify the Unit. Otherwise, an electric shock may result or the Unit may malfunction. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
