Automation Direct's new Dold
safety relays include:
LG5924 Series relays are single-channel E-stop relays designed to protect
people and machines in applications with emergency stop buttons. Available with
24, 110 and 230V ac 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 24V ac/dc, 110V ac, and 230V ac
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 secs. The 24V dc 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 24V
ac/dc, 110V ac and 230 V ac 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 24V dc 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.
