91-2-R112/24 VDC, 10 pnp/npn digital inputs, 1 analog input, 3 high-speed counter/shaft encoder inputs, 6 relay outputs, I/O expansion port, RS232/RS485 port Power supply Power supply, pnp (source) inputs protection device To avoid electromagnetic interference, mount the controller in a metal panel/cabinet and earth the power supply. Earth the power supply signal to the metal using a wire whose length does not exceed 10cm. If your conditions do not permit this, do not earth the power supply. pnp (source) high-speed counter H—Circuit protection device 1. All 10 Inputs can be set to pnp (source) or npn (sink) via a single jumper and appropriate wiring. 2. All 10 inputs can function in 12 VDC or 24 VDC; set via a single jumper and appropriate wiring. 3. npn (sink) inputs use voltage supplied from the controller’s power supply. 4. Inputs #0, #2 and #4 can each function as either high-speed counter or as part of a shaft encoder. In each case, high-speed input specifications apply. When used as a normal digital input, normal input specifications apply. 5. Inputs #1, #3 and #5 can each function as either counter reset, or as a normal digital input; in either case, specifications are those of a normal digital input. These inputs may also be used as part of a shaft encoder. In this case, high-speed input specifications apply.

The tables below show how to set a specific jumper to change the functionality of the controller. To open the controller and access the jumpers, refer to the directions at the end of these specifications. Incompatible jumper settings and wiring connections may severely damage the controller. Digital inputs type Power supply voltage Digital inputs voltage Analog input type •Default factory setting In this figure, the jumper settings will cause the controller to function as follows: Digital inputs: npn, 24VDC inputs Analog input: Voltage input Power supply: 24VDC Unitronics reserves the right to...
