Accessories for PVC controllers
Applications:
- Bake-out power switching. Use 3 relays for 3 phase power switching
- Direct valve operation
- Backing/balast pump operation (e.g. in response to Pirani pressure)
- Auto power up of equipment on pressure ok
- Power down in event of over-pressure
- Pump regeneration (e.g. timed cryo-pump recycling)
Specification:
- DIN rail mounted for ease of mounting in rear of rack
- Supplied with 1m lead with DB25 connector for direct connection to PVC (length can be extended by addition of standard through DB25 computer cable)
- 90-250Vac powered
- 7x change-over (normally open & normally closed contacts available) relays rated 16A @ 250Vac
- Terminals for digital inputs included
- Provides additional 12Vdc (max 250mA) for user wired interlocks
- Soldering-free connection to the PVC DB25 connector
- Ideal for system development or where interlock allocation changes frequently
- Type K thermocouple on M4 ring for flange mounting
- 3m long (EMTCK3) and 6m (EMTCK6) assemblies. Both assemblies comprise 2m length of bakeable cable; the rest non-bakeable. Other lengths on request
- Direct connection to PVC thermocouple (Type "K") module
