Products details
The Honeywell 10024/H/F is a dual-interface Enhanced Communication Module (ECM) designed for
seamless integration into the FSC (Fail-Safe Control) system, primarily serving three core
communication purposes: internal communication between redundant FSC Central Parts, external
data exchange with distributed control systems (DCSs), and connections to peripherals like FSC user
stations or printers. As a critical communication bridge, 10024/H/F relieves the FSC central processor
of communication tasks via its dedicated on-board processor and memory, ensuring optimal system
responsiveness and reliability in mission-critical industrial environments (e.g., oil & gas, chemical
processing).
10024/H/F features a two-part architecture—comprising a main board (10024/1/1) and two distinct
communication interfaces—to support diverse connectivity needs. 10024/H/F also includes robust
software capabilities, such as compatibility with multiple communication protocols (FSC-FSC, ModBus
RTU/H&B, RKE3964R), sequence-of-event recording (SER), and report generation, making 10024/H/F
adaptable to complex industrial control workflows. Additionally, 10024/H/F adheres to strict safety
and compliance standards (CE, UL, TÜV) to meet the requirements of safety-related applications up to
AK 8 (per DIN V 19250).

Hardware Protection & Stability
The 10024/H/F adopts a dual-part modular design, with a right-side main board (10024/1/1) and left-
side dual interfaces. The main board has a dedicated communication processor, 8 Mbit flash memory
(supports EPROMs like 27C512), and jumpers (J1/J2 for COM number, J3 for program source, J4/J5 for
EPROM type). It occupies 8 TE (8 HP) horizontal and 3 HE (3U) vertical rack space, operates on 5 Vdc
(500 mA current, <50 mV p-p ripple), and works in 0°C-60°C, ≤95% RH (non-condensing)
environments.
It integrates two interfaces: The H-interface (RS-422 with readback) is for internal redundant Central
Part communication, with 2 Mbaud baud rate, 1.5 m max cable length (Belden 9728/8314), male 9-pin
connector (pins 1=GND, 2=-TxC, etc.), no galvanic isolation, and self-test for fault-triggered Central
Part shutdown. The F-interface (Tri-State RS-232C) is for external communication (user stations/DCS),
with >6 kV galvanic isolation, up to 38.4 kbaud (15 m/10 m cable), female 9-pin connector (pins
1=DCD, 2=-RxD, etc.), and a watchdog circuit.
For integration, it needs a system bus (7-SBUS/12-SBUS/17-SBUS) jumper removed, supports FSC
software ≥2.78f, meets EMC standards (EN 50081-2/EN 50082-2), and must not be hot-swapped.
