Product Description P/N: 110741-00
Description
The 110741‑00 is a compact potted circuit module used for electric latch retraction in Von Duprin EL exit devices. It modulates the inrush current to the solenoid, enabling reliable door operation and latch control. Designed as a drop-in part (now replaced by part 050534), it provides protection against overcurrent and ensures secure power distribution in access control systems.

Information About 110741-00
The 110741‑00 is a potted circuit breaker / pulse-width modulator module originally used in Von Duprin EL electric latch retraction exit devices (Series 98/99/33A). It is designed to deliver a high-current pulse to activate the solenoid and then limit holding current to protect the circuit. The module features five wire leads and plugs into the device harness via built-in connectors. Although discontinued, its modern equivalent is the Von Duprin 050534 EL potted circuit breaker, which shares form‑factor and internal resistance characteristics. The device operates with a regulated 24 VDC power supply and is compatible with PS‑series power units.
Key Features:
- Part Type: Potted circuit breaker module (pulse-width modulator) integrated for EL latch retraction systems.
- Primary Function: Delivers initial high-current pulse to solenoid followed by lower holding current.
- Input Voltage: Designed for 24 VDC regulated power supply to EL latch systems.
- Compatibility: Fits Von Duprin Series 98, 99, 33A electric latch devices.
- Connector Interface: 5 wire leads with one 3‑pin and one 2‑pin molded connectors, plug‑in style.
- Replacement Unit: Successor module is Von Duprin 050534; direct swap with plug‑and‑play installation.
- Internal Resistance: Original approx. 75 Ω unloaded, ~22 Ω with solenoid attached; replacement about 30 Ω/5.5 Ω respectively.
- Testing Notes: Voltage readings differ when plugged in versus on power—best test is functional replacement.
- Form-Factor: Compact black resin‑potted housing approximately 5" × 1¼" × 7/16" including cables.
The 110741‑00 ensures the proper pulse modulation for safe and reliable solenoid activation in access control hardware.
