Introduction

An excellent value in its class, the B856 features a compact 1/16 DIN package, the
precision of 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 1, Interval 2, 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 .01 seconds to 9999 hours.

An available model's output features separate timed and instantaneous SPDT
contacts.

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.

Reliability is a key feature of the B856.
IEC Level 4 noise immunity ensures
flawless operation in harsh electrical
environments, while its IEC IP65
enclosure rating allows use in washdown conditions.

Wiring via an industry standard 11 pin socket and a power supply that can
accept 24 - 240 VAC or 24 VDC vastly simplify setup.
