LG5924 Series relays are single-channel E-stop relays designed to protect people and machines in applications with emergency stop buttons. Available with 24 VDC, 110 VAC, and 230 VAC coil voltages, the Category 2-rated relays are equipped with internal positive temperature coefficient resistor short circuit protection. Output configuration options include either two normally-open contacts, or three normally-open and one normally-closed contact. The normally-open contacts are safety contacts. Prices for LG5924 series safety relays start at $88.

LG5925 Series relays are dual-channel E-stop/safety gate relays designed for applications with emergency stop buttons and safety gates. Available with 24 VAC/DC, 110 VAC, and 230 VAC coil voltages, the Category 4-rated relays are equipped with internal positive temperature coefficient resistor short circuit and voltage-dependent resistor overvoltage protection. Designed with three normally-open positive guided safety contacts and one normally-closed monitoring contact, LG5925 relays provide a feedback circuit to monitor external contactors used for reinforcement of contacts, and feature monitored manual restart. Prices for LG5925 series safety relays start at $115.

The BH5928 Series relays are also designed for applications with emergency stops and safety gates. This dual-channel series provides one or two channels which can be monitored with the time delay function. Output configuration options include either three normally-open time delay positive guided safety contacts, or two instantaneous positive guided safety contacts and one normally-closed instantaneous monitoring contact. Three time delay options with potentiometer adjustment are available (depending on model) ranging from 0.1 to 30 seconds. The 24 VDC Category 4 relays are equipped with internal positive temperature coefficient resistor short circuit and voltage-dependent resistor overvoltage protection, and can be wired with or without cross-fail monitoring in the E-stop loop. Prices for the BH5928 series safety relays start at $198.

The BG5933 and BH5933 Series relays offer protection for applications with two-hand buttons or production machinery with dangerous closing movements. Available with 24 VAC/DC, 110 VAC, and 230 VAC coil voltages, the Category 4-rated relays are equipped with internal positive temperature coefficient resistor short circuit and voltage-dependent resistor overvoltage protection. These safety relays provide inputs for two pushbuttons, each with one normally-open and one normally-closed positive guided contact. Output configuration options include either two normally-open positive guided safety contacts and one normally-closed monitoring contact, or three normally-open positive guided safety contacts and one normally-closed monitoring contact. Prices for BG5933 and BH5933 series safety relays start at $139.

Category-4 rated light curtain controllers have also been added. Designed for light curtains with symmetric or asymmetric outputs, the LG5925 24 VDC light curtain controller features three normally-open positive guided safety contacts and one normally-closed monitoring contact and provides single or two-channel operation. The LG5925 light curtain controller is priced at $115. A multi-function features two normally-open positive guided safety contacts and one normally-closed monitoring contact; the controller can connect up to three light curtains, and offers protection, muting, and stepping modes. The multi-function light curtain controller is priced at $339.

The LG5929 extension module provides additional contacts for emergency-stop modules and safety gate monitors. Designed for one-channel or two-channel connection, the Category-4 rated extension module features five normally-open positive guided safety contacts and one normally-closed monitoring contact. The LG5929 extension module is priced at $95.
