CAUTION:
Risk of Electric Shock
– More than one disconnect switch may
be required to de-energize equipment before servicing.
Isolation:
I/O channel, power, and network circuits are isolated from each
other for common-mode voltages up to 250VAC, or 354V DC off DC
power ground, on a continuous basis (will withstand 1500VAC dielectric
strength test for one minute without breakdown). Complies with test
requirements of ANSI/ISA-82.01-1988 for voltage rating specified.
Installation Category:
Designed to operate in an installation in a Pollution
Degree 2 environment with an installation category (over-voltage
category) II rating.
Electromagnetic Interference Immunity (EMI):
Inputs/outputs have
demonstrated resistance to inadvertent state changes with interference
from switching solenoids, commutator motors, and drill motors.

CAUTION: Do not exceed
36VDC peak, to avoid damage
to the module.
External Fuse: Select a high
surge tolerant fuse rated for 1
Amp or less to protect unit.

Note that I/O channels are not
isolated channel-to-channel.
