•
Connector 1 provides four programmable digital
inputs terminals, two additional digital terminals
programmable as either input or output, a 24 V
DC terminal supply voltage, and a common for
optional customer supplied 24 V DC voltage
•
Connector 2 terminals (+)68 and (-)69 are for an
RS-485 serial communications connection
•
Connector 3 provides two analog inputs, one
analog output, 10 V DC supply voltage, and
commons for the inputs and output
•
Connector 4 is a USB port available for use with
the adjustable frequency drive

Description
24 V DC supply
voltage. Maximum
output current is 200
mA total for all 24 V
loads. Usable for
digital inputs and
external transducers.
Digital inputs.
Selectable for either
digital input or
output. Default setting
is input.
Common for digital
inputs and 0 V
potential for 24 V
supply.
(Optional) Safe input.
Used for STO.
Common for analog
output.
Programmable analog
output. The analog
signal is 0–20 mA or
4–20 mA at a
maximum of 500 Ω..
10 V DC analog
supply voltage. 15 mA
maximum commonly
used for potenti-
ometer or thermistor.
Analog input.
Selectable for voltage
or current. Switches
A53 and A54 select
mA or V.
