900TCK-0001 HC900 Terminal Block | Honeywell

Configured for 36-channel low-voltage signal termination in Honeywell ControlEdge HC900 system architectures, the Honeywell 900TCK-0001 (900TCK-0001 Terminal Block) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

The 900TCK-0001 36-channel terminal block routes analog and discrete low-voltage signals between field devices and matching HC900 I/O modules. Designed to maintain signal continuity across process networks using 4-20 mA HART loop protocol instruments, the assembly provides high physical dielectric isolation across terminal paths. This mechanical isolation minimizes stray current loop interference and prevents channel-to-channel noise cross-talk across densely packed cabinet connections.

Frequently Asked Questions

Q: Does the 900TCK-0001 require active backplane power or an external DC power input?

A: No, the 900TCK-0001 is a passive electromechanical terminal wiring assembly that functions without external DC or AC power.

Q: How many field wiring channels does the 900TCK-0001 terminal assembly support?

A: The terminal assembly features 36 individual connection points dedicated to low-voltage signal wiring.

Q: Can the terminal block be removed without disconnecting individual field wires?

A: Yes, the removable terminal block design allows full detachment from the corresponding I/O module faceplate while keeping field wiring terminations intact.

Field Installation Guidelines

1. Disconnect all external field loop voltage sources before landing or removing conductors on the 900TCK-0001 terminals.
2. Strip wire jacket insulation to the standard length and secure conductors into terminal clamps, verifying proper mechanical tension.
3. Route 4-20 mA signal wires away from high-voltage AC power lines to prevent induced field noise.
4. Align the terminal assembly squarely with the target HC900 I/O module connector and tighten retaining hardware to ensure firm contact engagement.
