Instruments & Controls

The Signet 8860 Two-Channel Conductivity/Resistivity Controller accommodates two separate and independent input sources. To control the process, the 8860 is equipped with four dry contact relays and three 4 to 20 mA output loops. 

The 8059 External Relay Modules supplement the output capabilities of certain host instruments such as the 8900 Multi-Parameter Controller. AC-powered versions accept universal line voltage, and also provide 24 VDC output that can be used to power the host instrument or other device(s).

- Relay Outputs: 2 or 4 external contact relays. SPDT 250VAC/30VDC/5A

- Compatible Instruments: 8900 (S3L Instruments only)

Relay Module.This module adds two programmable dry-contact relays to the standard Open Collector output in the base unit.
