Chapter 1. The Kaye Validator
1.4.2 Sensor Input Modules (SIMs)
The Validator uses Sensor Input Modules to provide secure connection of sensors to the
Validator while protecting the electronics from draft, dust, humidity, electrical noise and
mechanical shock. SIMs are designed to be wired once and used repeatedly. You can wire
SIMs yourself, or buy pre-wired SIMs to reduce preparation time. Once the SIMs are wired,
you can calibrate multiple harnesses at the same time and store them for later use.
Figure 3: Sensor Input Module
The Validator can be configured for up to 4 SIMs. Each SIM has:
•
12 sensor input connections
•
A memory chip to store calibration offsets, SIM serial number, slot location, and the serial
number of the Validator measurement board where calibration was performed
•
A cold junction reference RTD to maintain measurement accuracy in different
environmental conditions
Using 4 SIMs, you can attach up to 48 inputs in any combination of thermocouples, voltage,
or current inputs. A dedicated 4-20 mA SIM is also available with 12 4-20 mA inputs and
one connection for an external power supply.
