The ABB 216VC62a/P1000 (HESG324442R112) is a processor unit relay card designed for ABB’s Symphony Plus and legacy Harmony/INFI 90 control systems, serving as a high-performance processing and relay interface for industrial DCS applications. It handles real-time logic execution, signal processing, and relay control for process automation in demanding environments like power generation, oil & gas, and water treatment, featuring a robust 32-bit processor and integrated relay outputs for critical interlocking and trip functions.
Product Parameters
The card integrates a 32-bit 80486DX-2 processor (66 MHz class), with onboard RAM for runtime data and Flash EPROM for firmware/settings. It supports 16 analog input channels (0-10 V, 0-20/4-20 mA, thermocouples), 32 digital I/O points, and multiple relay outputs (8-16 tripping/auxiliary relays with potential-free contacts). Power is 24 V DC auxiliary (redundant capable), consuming ~15 W typical. Communication includes RS-423 PC interface, internal IEEE P896 bus (16-bit multiplexed), and PROFIBUS-DP/MODBUS/HART protocols. Dimensions are 35.6 cm x 2.5 cm x 38.1 cm at 0.7 kg; environmental ratings cover -20°C to +70°C operation, IP20 protection, 2g vibration (2-150 Hz), and EMI per IEC 61000 standards.
Datasheet Overview
Datasheet specs highlight TMR-like fault tolerance via dual-processor integrity checks, 600/720 Hz sampling (50/60 Hz), and 1 ms SOE resolution. Analog accuracy is ±0.5% FS, with 16-bit resolution; relays offer surge-protected contacts (5 A/250 VAC). Bus supports 32 masters with handshake/data integrity; settings stored non-volatile. Mechanical design fits 19″ racks (2U height), hot-swappable; certifications include CE/UL, SIL 2/3 capable per IEC 61508.
Origin
Manufactured in Sweden at ABB’s process automation facilities.
