Voltage considerations
Ribbon cable connections are generally good for up to 1000VDC and 700 VAC, while Discrete type connections are good for up to 1500 VDC and 1000VAC.
CH2-CR Converter
The CH2-CR Converter (Part #ACH2-CR) was developed for customers to plug their existing CR 64 pin connectors onto the CH2 system. The CH2-CR Converter card mounts onto the front of the CH2 tester, converting two 32 pin Euro-DIN style connectors to a single 64 pin header like that on a CR. Typical cost is $1.18 per test point, connector only.
Adapter Panel
A Turn-Key Solution for more complex systems is our adapter panel for the CH2. Both internal and external connectors and wiring are replaceable, inside and out. Typical cost is $5.00 per test point (800 points, $4000.00)
