Note: The DS3800HPIB1F1D is functionally identical to the base DS3800HPIB and other HPIB variants in all key specifications. The suffix indicates a minor calibration or firmware variation.
Selection
| Scenario | Choice |
|---|---|
| Output-only actuation (valves, solenoids) | DS3800HPIB1F1D – 16 outputs, no inputs. |
| Inputs + outputs required | Use DS3800HPBC (16 in / 8 out) or DS3800HPBD (32 in / 16 out). |
| Digital control (24V only) | Use DS3800HP1B (combined I/O). |
| Temperature monitoring | Use DS3800HMPK series. |
| TMR | Three identical 1F1D modules. Do not mix revisions. |
| Non-GE | Do not use – VME only. |
Critical Precautions
-
Authenticate – Check GE hologram, serial number.
-
ESD – Wear grounded wrist strap.
-
Backplane – Verify +5V, +15V, -15V before insertion.
-
Voltage Selection – Verify field voltage (24V or 125V) matches module configuration.
-
Wiring – Use shielded cable; maintain separation from AC power.
-
Load Check – Outputs rated 0.5A continuous; 1.0A peak. Verify connected load.
-
External Fusing – GE recommends external fuses on each output for protection.
-
Torque – 0.5-0.6 Nm.
-
Temp – Keep rack <70°C.
-
Firmware – Factory-programmed; cannot be field-updated.
-
Sourcing – Obsolete; source refurbished from certified GE repair centers.
Final Summary
The General Electric DS3800HPIB1F1D is a high-current digital output module for GE Speedtronic systems, offering 16 isolated outputs with selectable 24V or 125V DC field power. It is ideal for driving solenoids, valves, contactors, and alarm devices where inputs are handled by separate modules. It is functionally identical to other HPIB variants. For combined I/O applications, use DS3800HPBC or DS3800HPBD. For temperature monitoring, choose DS3800HMPK. Source from certified repair centers.
