, bipolar, differential
±10V / 0-20mA or 4-20mA.
Important: 0-20mA or 4-20mA operation
requires that switch S9, S10, and S11 on
the Control board be in the “Off” position.
Drive damage may occur if the switch is not
in the correct position based on the type of
input signal. Refer to Table 1.L on
page 1-33.
Max ±10V, Max 0.25mA.

A digital input (1-8) must be configured for “Enable”.
(2)
When using the internal +24V DC supply (terminal 19) for digital inputs 1-4, you must connect the digital input common (terminal 16) to the +24V supply common
(terminal 18).
(3)
The total current draw is the sum of encoder power, digital outputs and any other loads connected to terminal 19.
