AIN-200
WBPEEUI240751C0 2 - 3
The AIN-200 block supports 16 isolated input channels that
operate in voltage mode only. Each input channel is individu-
ally software configurable for voltage range or thermocouple
type. Cold junction compensation for thermocouple inputs is
included. The block supports redundant I/O electronics.

NOTES:
1. All specification values are maximums unless stated otherwi se.
2. Maximum error includes effects of nonlinearity, repeatability, hysteresis, noise, and quantization error.
3. This is the rate at which the block reads and updates values. The rate at which the values are actually read and become avail-
able to the system depends on the scan cycle of the controller.
