The DRM Series of pluggable relays is available in two and four changeover versions for AC and DC coil input voltages. The relay contacts are made from a heavy electroplated silver alloy that measures 270 microns thick and allows for a wide range of loads from a few milliamps up to 10A per contact. In addition, the devices offer full load switching capability over a wide temperature range (-40°C to +60°C) without the need for derating, according to the company. The products can also be used in temperatures up to +80°C with derated switching capabilities.
The ESR5 safety relay is compatible with a range of safety devices, including emergency stops, rope pulls, and two-hand control stations. In the event of a fault or activation of the safety device, the enable paths are switched off. Available in single- and dual-channel versions, the product detects faults that occur in the control circuit, including ground fault, cross connection fault, or wire breakage.

Industrial safety relays
The Dold family of safety relay devices is designed for industrial applications. The LG5924 Series includes single-channel E-stop relays designed to protect users and machines in applications with emergency stop buttons. Available with 24VDC, 110VAC, and 230VAC coil voltages, the Category 2-rated products are equipped with internal positive temperature coefficient resistor short circuit protection. The LG5925 Series of dual-channel E-stop/safety gate relays is designed for applications with emergency stop buttons and safety gates. Available with 24VAC/DC, 110VAC, and 23VAC coil voltages, the Category 4-rated products feature internal positive temperature coefficient resistor short circuit and voltage-dependent resistor overvoltage protection. The BH5928 Series is also designed for applications with emergency stops and safety gates. These dual-channel relays provide one or two channels that can be monitored with the time delay function. The BG5933 and BH5933 Series of relays offer protection for applications with two-hand buttons or production machinery with dangerous closing movements.
