AIN-300
WBPEEUI240751C0 2 - 5
AIN-300
Isolated RTD In
The AIN-300 block interfaces three-wire RTD analog input sig-
nals. It supports 16 isolated input channels individually soft-
ware configurable for RTD type (refer to Table
2-4 for types
supported). The block supports redundant I/O electronics.
Full scale resolution 18 bit resolution for –10 to +10 VDC range or –100 to
+100 mVDC range

NOTES :
1. All specification values are maximums unless stated otherwise.
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.
4. Remote field powered I/O may need external protection.
