Hot Swap
Yes. Module can be swapped while RTU is running. Hot
swap will not cause a Warm Start. Inputs are cleared in
RTU memory while module is removed.
Compatibility
One range setting for all channels when used with a PC-1
or CP-11/12/21 processor.
Individual range setting for each channel when used with a
CP-30 processor.
1
) AI-10 only.
2
) For AI-10 V2.x only unipolar current ranges are recommended for use. Bipolar ranges are not
calibrated for current measurement and their accuracy can reach 1.4% of full scale when used to
measure current.
3
) For AI-10 V2.x only bipolar voltage ranges are recommended for use. Unipolar ranges are not
calibrated for voltage measurement and their accuracy can reach 1.4% of full scale when used to
measure voltage.
4
) Analogue Input channels can be modified from low impedance to high impedance by disconnecting
the 250 Ω channel resistor.
5
) The ±10 V input range can only be used on an AI-10 input channel if the current sensing resistor
has been disconnected. Resistors have already been disconnected in an AI-10-V.
