T-type
T-type
terminal boards typically fan the sensor inputs to three separate I/O packs. Usually, the TMR board hardware votes the
outputs from the three I/O packs. T-type boards contain two, 24-point, barrier-type, removable, terminal blocks. Each point
can accept two 3.0 mm (0.12 in) (#12AWG) wires with 300 V insulation per point with either spade or ring-type lugs. In
addition, captive clamps are provided for terminating bare wires. Screw spacing is 9.53 mm (0.375 in) minimum and
center-to-center.
Note
Some application-specific TMR terminal boards do not fan inputs or vote the outputs.
Barrier-type Terminal Blocks
These terminal blocks have the following features:
•
Black in color with white number labels
•
Terminal rating is 300 V, 10 A
•
UL recognized
•
Recommended screw tightening torque is 7 lb-in (0.8 Nm).
