The 5-pole captive screw input connector and four 3-pole captive

screw output connectors are included with the unit, but you

must supply the cable. Extron recommends its CTL Series cable,

part #22-148-nn (non-plenum bulk rolls), 26-119-nn (plenum

Input connections

Inputs — Connect the 12 VDC source to the common voltage (C)

terminal of the 5-pole captive screw connector. Connect the

appropriate input terminal (1 through 4) to the digital output(s) of

the IPL T SF24, MLC 104 IP Plus, or other device.

C Connect +12 VDC to the C pin only and

connect the return to one or all of the Input pins

(1 through 4) for the relays that you will use.

Reversing the connections can damage the power
