GE IS220PDIIH1A Isolated Discrete Input Module

FAQ

Q1. What type of module is IS220PDIIH1A?
It is an isolated discrete input module that processes field binary signals in GE Mark VIe turbine and industrial control systems.

Q2. How many discrete inputs does it support?
It typically includes 16 isolated discrete input channels.

Q3. What signal voltage does this module handle?
It is designed to work with discrete field signals, commonly 24 V DC system voltage.

Q4. Does the module provide electrical isolation?
Yes, all inputs are galvanically isolated to help protect the backplane and controller from field transients and faults.

Q5. Can it be hot‑swapped during operation?
Modules like this in the Mark VIe family are often hot‑swappable within the rack when used with proper terminal boards and support hardware.

Q6. What environmental conditions can it tolerate?
It operates reliably in industrial environments from about -30 °C to +65 °C with standard humidity tolerance.

Q7. How is this module mounted?
It mounts in a VME or similar rack/backplane slot within a Mark VIe control system cabinet.

Q8. What systems is it compatible with?
It is used in GE’s Mark VIe / Speedtronic distributed control and turbine control environments, integrating with terminal boards and Ethernet communication networks for discrete I/O processing.
