GF Signet 8059 External Relay Modules

• External relays controlled by host instrument
• AC and DC powered versions
• DC power output (AC versions)
• DC power passthrough (DC versions) to simplify wiring
• Digital (S3L) passthrough to simplify sensor wiring
• Red LED annunciators for each relay
• Green LED indicators for power and digitial (S3L) data transfer
• Relays may be tested locally, and also via the host instrument

GF Signet 8059 External Relay Modules supplement the output capabilities of certain host instruments
such as the GF Signet 8900 Multi-Parameter Controller. AC-powered versions of the GF Signet 8059
External Relay Module accept universal line voltage and also provide 24 VDC output that can be used
to power the host instrument or other device(s). The host instrument controls relay operation by way
of a single digital (S3L) connection.

Each GF Signet 8059 External Relay Module features compact plastic housing which is DIN rail
mountable and includes LED annunciators for each relay, plus one each for power-on and data
transfer or test mode.
