Terminals and Internal Connection Diagram

The iSMA-B-MAC36NL controller is supplied by 24 V AC/DC. The power supply block is separated. The grounding pin located next to power supply terminals must be connected to the ground.

The device has 36 local I/O on board:

• 8 digital outputs (8 DO), relay output with max. load 3 A @ 230 V AC/30 V DC;
• 8 analog outputs (8 AO), voltage output 0-10 V DC maximum load up to 20 mA;
• 16 universal inputs (16 UI), temperature, voltage, current, resistive, or dry contact;
• 4 digital inputs (4 DI), dry contact inputs or fast counter up to 100 Hz.
