G4 I/O family
The G4DA9 time proportional output (TPO) module provides digital control from a mistic analog brick or modular controller. Each module is optically isolated to 4,000 volts (transient) from field devices and features point-to-point electrical isolation. The G4DA9 switches 5-60 VDC. Together with a Power-series solid-state relay (SSR), the G4DA9 can be used to control heater circuits.
