An excellent value in its class, the B856 features a compact 1/16 DIN
package, precise digital setting, versatile functionality, and a
straightforward button-per-digit interface. It can be easily programmed
to perform any standard timing operation: On-Delay, Off-Delay, Interval,
or Repeat Cycle. A unique On-Delay/ Interval Mode can, in many cases,
perform the function of two separate timers. Output is via DPDT relay
contacts.
Five selectable time ranges and a programmable decimal point provide
preset times ranging from 0.01 seconds to 9999 hours. A standard model
features a timed DPDT contact output while another model includes
separate timed and instantaneous SPDT contacts. All are rated for 5 Amp
loads.
Simplicity of operation is maintained while still providing a high
level of functionality. All programming is done through the front
panel, with an intuitive button-per-digit keypad that makes entry of
preset times quick and easy. A crisp dual line LCD display lets the
operator readily view elapsed or remaining cycle time as well as the
preset value. Prominent annunciators indicate information such as the
time range and the status of the input and outputs.
