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-perdigit interface.
It can be easily programmed to perform any standard timing operation: On-Delay, OffDelay, 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.
Features
• Field programmable choice of 6 operating
modes
• 5 selectable time ranges with resolution down
to 0.01 seconds
• High Contrast LCD display indicates both
process time and preset value
• Simple button per digit interface
• Programmable security levels prevent
unauthorized setpoint or program changes
• Universal Power Supply (24 - 240 VAC,
24 VDC)
• External Start and Reset Inputs
• UL and CUL recognized, CE marked
• IEC IP65 rated front panel
• Model with Instantaneous contacts also
available

To wire the unit, an 11 pin socket is required. The
unit can then either be DIN rail mounted or panel
mounted using the supplied mounting bracket. For
panel mounting, place the unit in the cutout, then
slide the bracket forward over the rear of the unit so
that the tabs catch in the grooves on the housing and
the bracket is as far forward as possible. Tighten the
panel mount screws until there is a snug fit against
the panel. Do not overtighten.

FRONT PANEL OPERATION
I/O Status Indicators
Illuminates to display when an input or
output is active: "IN' for the start input,
"OUT" for the timed output, and "RST" for the
external reset signal.
Time Indicators
The word "Timing" flashes when a timing
function is taking place. The applicable
arrow also lights to indicate if the display
is set to time up or time down.
Time Value
Indicates the elapsed/remaining time to
preset.
Edit Key
Many of the parameters in Program Mode require selection of a
specific choice as opposed to a numeric value. The Edit key is
used to scroll through the available choices. In Operation mode,
the Edit key can be pressed simultaneously with the Program key to
reset the timer.

releasing the key will scroll the display from one parameter to the
next.
Time Range Indicator

Numeric Keys
Each of the number keys is used to
increment or decrement the value of the
corresponding digit of the preset or a
parameter value (increments if unit is set
in time up mode and decrements if set in
time down mode).

PROGRAMMING
PROGRAM MODE
• Enter the Program Mode by holding down the "P" key for 3 seconds
• Press the "P" key to move the top display from one parameter to the next
• Press the "E" key to scroll the bottom display through the available choices for that parameter
• While in Program Mode the unit will stop timing, and the output will retain its last state. The new
settings will only become effective after returning to Operation Mode by holding down the "P" key
for 3 seconds

Interval Time: Sets the amount of time the output will be active after the On-Delay function has timed
out. Use the 1 through 4 keys to set the value in a range from 0.1 to 999.9 seconds.
Note: This parameter will only appear if Delay/Interval is chosen as the Operating
Function
Time Range: Sets the unit of measure for the time values that will be shown on the display in
Operation Mode. Choices are:
• Seconds
• Minutes
• Hours
• Minutes:Seconds
• Hours:Minutes
Decimal Position: Sets the decimal position for the time display. Choices are: no decimal point (0),
1/10ths position (0.0), or Hundredths position (0.00). The time range selected in the previous
parameter will remain illuminated for reference.
Note: This parameter will not appear if Minutes:Seconds or Hours:Minutes is
selected as the time range

Power Reset Enable: After a loss of power, the unit can be programmed to either reset upon
reapplication of power (On) or continue from the point of power interruption (Off).
Front Panel Reset Enable: When active (On), the timing operation can be reset in Operation Mode by

Timing begins on the leading edge of the start signal. A cycle is initiated where
the output will be OFF for the preset time (T), then ON for the preset time. This
cycle will continue until a reset signal is applied, start signal is removed or power
is interrupted.* The unit can also be programmed for the timing sequence to
begin with an ON cycle.
* The Power Reset parameter in Program Mode can be set so that a timing
sequence will not be reset upon power interruption but instead continue
on when power is restored.

The delay cycle begins upon application of the start signal. The output will
activate at the completion of the preset time (T1). Upon activation of the
output, the Interval cycle will begin. The output will be deactivated at the end
of the Interval time (T2). T1 is the primary preset value and is set in Operation
Mode. T2 is set in Program Mode in a range from 0.1 to 999.9 seconds. The
timing sequence and output can also be reset through the reset input or
