Performance & Environmental Resistance

• The board uses hardware filters to suppress spikes and high-frequency noise on inputs.
• The device provides robust surge and transient protection via input conditioning circuits.
• The conformal PCB coating increases humidity and contaminant tolerance in rugged environments.

Installation Guide

• Mount the TDBT on a DIN rail or secure the sheet metal carrier inside a control cabinet.
• Wire input circuits to the lower terminal block TB2 and relay outputs to upper TB1 terminals.
• Use #18 AWG conductors for direct wiring to terminal blocks and maintain shield grounding per practice.

Relay Options & Configuration

• Install the relay option board into connectors JW1 and JW2 to enable 12 form-C relays.
• Option-board jumpers control relay contact types and factory assembly includes all six jumpers.
• Remove specific jumpers when you require dry contacts and no internal power distribution.
