Digital inputs 10 pnp (source) or npn (sink)
inputs. See Note 1.
Nominal input voltage 12VDC or 24VDC.
See Notes 2 and 3.
Input voltages for pnp (source):
For 12VDC <3VDC for Logic 0
>8VDC for Logic 1
For 24VDC <5VDC for Logic 0
>17VDC for Logic 1
Input voltages for npn (sink):
For 12VDC >8VDC/<1.2mA for Logic 0

Input current 4mA@12VDC
8mA@24VDC
Input impedance 3KW
Response time 10mS typical
(except high-speed inputs)
Galvanic isolation None
Input cable length Up to 100 meters, unshielded
High-speed counter Specifications below apply when
inputs are wired for use as a high-
speed counter input/shaft
encoder. See Notes 4 and 5.
Resolution 16-bit
Input freq. 10kHz max.
Minimum pulse 40µs
Notes:
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.

ower supply, pnp (sourse) inputs
Note:
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.
Using a wire longer than 10cm will cause signal interference.

Jumpers Settings
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.
Important:
Incompatible jumper settings and wiring connections may severely damage the controller.
Opening the controller enclosure
1. Locate the 4 slots on the sides of the enclosure
2. Using the blade of a flat-bladed screwdriver, gently pry off the
back of the controller as shown in the figure below, exposing the
controller's board.
