G-DRY Series Dry Output modules offer true Dry Contact switching of AC/DC large and small signals. Its industrial -40-+85 deg. C. temperature rating, fully-encapsulated circuitry, direct compatibility with industry standard I/O mounting racks, and high reliability make this series ideal for harsh industrial control applications. The active-low input is directly compatible with open-collector driver circuits.  Models for 5V operation are also compatible with TTL and CMOS logic. These modules can also be configured for PLC Logic compatibility.

The versatile DRY CONTACT output has zero OFF-state leakage current offering direct compatibility to control solid state input circuits. This series employs a HI-REL reed relay with excellent cycle life (100 million mechanical operations), low ON-state resistance and high power factor switching.  These modules can control both large and small signals, eliminating the need to specify separate AC and DC module types.

This series offers both FORM 1A (N.O.) and FORM 1B (N.C.) dry contact relay types.  System designers can select among these types to pre-configure critical I/O points for default power-down states, allowing for fail-SAFE I/O system operation. The standard relay configuration is normally open. 

The G-DRY Series is compatible with I/O Racks from Brentek (DIN-102R, HDXTM, and UNI), Opto 22 G4 racks, Grayhill 70G Racks, and others.  Industry-standard control voltages of 5V, 12V, 15V, and 24V are available as:

  • G-DRY5
  • G-DRY12
  • G-DRY15
  • G-DRY24
