BENTLY NEVADA 125720-01 Spare 4-Channel Relay Output Module

Description

The BENTLY NEVADA 125720-01 is a 4-Channel Relay Output Module belonging to the BENTLY NEVADA 3500 Series I/O Modules, designed for industrial automation systems to support logic control, signal transmission, and equipment protection. This full-height module features 4 independent programmable channels, each capable of executing voting logic with alarm drive logic programmed via AND and OR functions, accepting alarm inputs (alert and danger status) from any monitor channel or combination of channels within the rack using dedicated 3500 rack configuration software.

Key technical specifications include: 24VDC input voltage, 24V DC load voltage, 2A per-channel load current, 250 VA contact capacity, 250 VAC/VDC switching voltage, and 10 A switching current. It supports TTL/CMOS level input signals and relay contact output signals, with a response time of less than 1ms and RS-485 communication interface. The module is equipped with 8 KB NVRAM, uses solid-state single-pole double-throw (SPDT) relays, and has an epoxy-sealed construction. Its operating temperature range spans -40 degrees Celsius to 85 degrees Celsius, with storage temperatures matching this range, and it measures 166mm x 112mm x 36mm, weighing approximately 375g. Multiple units can be installed in any slot to the right of the Transient Data Interface Module in the rack.
