Trusted TMR Field Termination and Isolation
The T8842 provides 40 field termination channels divided into five independent power groups. Each group has dual 24 VDC redundant supply feeds. Individual channel fuses provide overcurrent protection, while signal resistor conditioning supports field signal status monitoring. Opto/galvanic isolation provides electrical separation between field wiring and the associated control interface.
The assembly can interface 2-wire and 3-wire devices including 4-20 mA field instruments, fire and heat sensors, gas detectors, and manual call points. Its DIN rail construction supports horizontal or vertical installation.
Frequently Asked Questions
Q: How are the T8842 channels arranged?
A: The assembly has 40 channels organized into five power groups, with eight channels assigned to each group.
Q: Does each field channel have individual protection?
A: Yes. Each channel uses an individual plug-in fuse for field-loop overcurrent protection.
Q: What mounting method is specified for the T8842?
A: The assembly is designed for TS32 or TS35 DIN rail mounting and can be installed horizontally or vertically.
Field Installation Guidelines
Install the T8842 on a mechanically secure TS32 or TS35 DIN rail with adequate clearance for field wiring and fuse access. Verify the 24 VDC supply polarity and redundant feed connections before energization.
Separate field signal wiring from high-current or switching conductors where practical. Maintain consistent cable shielding and termination practices for analog loops. Connect shields according to the system grounding design and avoid creating unintended ground loops.
Check each field-channel fuse and wiring termination before commissioning. Confirm that the connected field device type and loop configuration correspond to the intended channel arrangement. Do not exceed the specified group current capacity or channel current recommendation.
