ABB 216GD61A HESG324428 Auxiliary Relay And Optocoupler Module

ABB 216GD61A HESG324428 Auxiliary Relay And Optocoupler Module

Functional Description

The 216GD61A  is used in the compact version REG216. It provides eight tripping relays, each with two

powerful, potential-free tripping contacts (with surge circuits), 16 auxiliary relays and 16 optocoupler input

circuits. Max. four assemblies can be provided. 

· 16 opto-coupler inputs:

for controlling the tripping unit 216DB61.

Contrary to the unit 216GD61, the unit 216GD61a all channels 1 to 16 are designed for the voltage range

82...312 V DC Channel 1 is intended as a reset I/P and is activated by the optional reset button. All the I/P's

can be adapted for other voltages in the range 20 V DC to 312 V DC by fitting a series resistor with the

corresponding value.

· 8 tripping relays:

controlled by the tripping unit 216DB61. In each case, one circuit is connected to terminals, which is made by

two contacts in series.

· 16 signalling relays:

controlled by the binary O/P unit 216AB61. The N/O contact of all the relays and the N/C contact of relays

1...4 are connected to terminals.
