Functional Description

IS230TNRLH1E is a Relay Output Assembly manufactured and designed by General Electric. It is a part of the Mark VIe Control System. The board is intended for DIN-rail or flat installation. The board accepts 24 group isolated contact inputs from an external source with a nominal 24, 48, or 125 V dc wetting voltage. To protect against surge and high-frequency noise, the contact inputs have noise suppression. TDBS has 12 form-C relay outputs and can accept various option cards to expand relay functions.

Operation

• They are calibrated for wetting voltages of 24, 48, and 125 V dc. The input wetting voltage ranges are as follows: 16 to 32 V dc, 32 to 64 V dc, and 100 to 145 V dc. The threshold voltage is equal to half of the wetting voltage.
• Contact input currents are limited by resistance to 2.5 mA on the first 21 circuits and 10 mA on circuits 22-24. TDBSH2's 24 V dc supply is current limited to 0.5 A by resetting polymer positive temperature coefficient fuses. Filters at each input near the point of signal entry reduce high-frequency noise and suppress surge.
• The discrete input voltage signals are routed to the I/O processor, which converts them to digital signals and sends them to the controller via optical isolators.

Product Attributes

• Input filter: Hardware filter, 4 ms
• Fault detection in I/O board: Loss of contact input wetting voltage, Non-responding contact input in test mode
• AC voltage rejection: 12 V rms at 24 Vdc wetting voltage.
• Number of relay channels: 12 relays
• Rated voltage on relay contacts: Nominal 24 V dc, 48 V dc, or 125 V dc, Nominal 120 V ac or 240 V ac
