Automation Direct's new Doldsafety relays include:
LG5924 Series relays are single-channel E-stop relays designed to protectpeople and machines in applications with emergency stop buttons. Available with24, 110 and 230V ac coil voltages, the Category 2-rated relays are equippedwith internal positive temperature coefficient resistor short circuitprotection. Output configuration options include either two normally-opencontacts, or three normally-open and one normally-closed contact. Thenormally-open contacts are safety contacts. Prices for LG5924 series safetyrelays start at $88.

LG5925 Series relays aredual-channel E-stop/safety gate relays designed for applications with emergencystop buttons and safety gates. Available with 24V ac/dc, 110V ac, and 230V accoil voltages, the Category 4-rated relays are equipped with internal positivetemperature coefficient resistor short circuit and voltage-dependent resistorovervoltage protection. Designed with three normally-open positive guidedsafety contacts and one normally-closed monitoring contact, LG5925 relaysprovide a feedback circuit to monitor external contactors used forreinforcement of contacts, and feature monitored manual restart. Prices forLG5925 series safety relays start at $115.

The BH5928 Series relays are alsodesigned for applications with emergency stops and safety gates. Thisdual-channel series provides one or two channels which can be monitored withthe time delay function. Output configuration options include either threenormally-open time delay positive guided safety contacts, or two instantaneouspositive guided safety contacts and one normally-closed instantaneousmonitoring contact. Three time delay options with potentiometer adjustment areavailable (depending on model) ranging from 0.1 to 30 secs. The 24V dc Category4 relays are equipped with internal positive temperature coefficient resistorshort circuit and voltage-dependent resistor overvoltage protection, and can bewired with or without cross-fail monitoring in the E-stop loop. Prices for theBH5928 series safety relays start at $198.

The BG5933 and BH5933 Series relays offer protection for applications with two-hand buttons orproduction machinery with dangerous closing movements. Available with 24Vac/dc, 110V ac and 230 V ac coil voltages, the Category 4-rated relays areequipped with internal positive temperature coefficient resistor short circuitand voltage-dependent resistor overvoltage protection. These safety relaysprovide inputs for two pushbuttons, each with one normally-open and onenormally-closed positive guided contact. Output configuration options includeeither two normally-open positive guided safety contacts and onenormally-closed monitoring contact, or three normally-open positive guidedsafety contacts and one normally-closed monitoring contact. Prices for BG5933and BH5933 series safety relays start at $139.

Category-4 rated light curtaincontrollers have also been added. Designed for light curtains with symmetric orasymmetric outputs, the LG5925 24V dc light curtain controller features threenormally-open positive guided safety contacts and one normally-closedmonitoring contact and provides single or two-channel operation. The LG5925light curtain controller is priced at $115. A multi-function features two normally-openpositive guided safety contacts and one normally-closed monitoring contact; thecontroller can connect up to three light curtains, and offers protection,muting, and stepping modes. The multi-function light curtain controller ispriced at $339.

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