GE IS400TBCIS2C Contact Input With Group Isolation Terminal Board
Functional Description
The IS400TBCIS2C Contact Input with Group Isolation (TBCI) terminal board accepts 24 dry contact inputs
wired to two barrier-type terminal blocks. For contact excitation, dc power is wired to TBCI. The contact
inputs have noise suppression circuitry to protect against surge and high-frequency noise.
Compatibility
The TBCI supports simplex, dual, and TMR redundancy. One, two, or three I/O packs can be plugged directly
into the TBCI.
| Version | Wetting Voltage | Hazardous Locations Capability | IEC61508 certified with YDIA pack |
| TBCIS2C | 24 V dc | Class 1, Div 2 / Class 2, Zone 2 / ATEX For ratings and further details, refer to the Mark VIeS Functional Safety System Equipment in Hazardous Locations (HazLoc) Instruction Guide (GEH-6861). |
Yes |
| TBCIS3C | 48 V dc |
Installation
Connect the wires for the 24 dry contact inputs directly to two I/O terminal blocks on the terminal board.
These blocks are held down with two screws and can be unplugged from the board for maintenance. Each
block has 24 terminals accepting up to #12 AWG wires. A shield terminal strip attached to chassis ground is
located immediately to the left of each terminal block.
In a Simplex system, connect the I/O pack into the TBCI connector JR1. In a Dual system, plug the I/O packs
into JR1 and JS1. In a TMR system, plug the I/O packs into JR1, JS1, and JT1. The I/O pack(s) attach to side-
mounting brackets. One or two Ethernet cables plug into the I/O packs. Connect TBCI to the contact
excitation voltage source using plugs JE1 and JE2.
