TS-7840 Terminal Block

From Technologic Systems Manuals

The TS-7840 includes two removable terminal blocks with 8 pins each.

This header includes 3 low side switches and one high side switch.

The low side switches can sink up to 700mA and support up to 30VDC. These IO feature a shared circuit breaker that will trip if the combined sinks total over 1000mA.

The high-side switch outputs the 10-48VDC source used to power the boards and will supply up to the 48VDC input max. This IO features its own circuit breaker that will trip at 330mA.
