ProtEX-MAX PD8-6210 Explosion-Proof Analog Input Batch Controller
Instruction Manual
7
Introduction
The ProtEX-MAX PD8-6210 is an explosion-proof
analog input batch controller ideal for simplifying
independent batch control operations where local
control is preferred to expensive and expansive plant
operation systems. The controller features a dual-line
display, with a main display 0.60" (15 mm) high, and a
second display of 0.46" (12 mm) high superluminous
LED digits, which can be read in any lighting
condition, including direct sunlight. The controller is
housed in a die-cast aluminum, field-mountable,
NEMA 4X/IP68 rated enclosure for convenient indoor
and outdoor installation.
The controller comes programmed for easy start,
pause, stop, and batch size (preset) changes. The
second display can be programmed to display rate,
grand total, batch count, or preset by cycling the Stop
(F3) button. Digital inputs come standard.
Single and multi-stage batching is possible with four
(4) on-board relays. Each batch control relay may
have a unique preclose amount when used for
multi-stage batching. Manual start batching is default,
but automatic batching with a restart after a
programmed time delay from the completion of the
last batch is also possible.
Overrun correction adjusts the closing of the batch
control relays to adjust for inaccuracies from batch to
batch. This increases accuracy over time as systems
wear out. The overrun correction feature is capable of
compensating for inaccuracies of up to 1% of the
programmed preset value.
The controller accepts current and voltage signals
(e.g. 4-20 mA, 0-10 V).
The PD8-6210 batch controller comes with four SPDT
relays, a 4-20 mA output, two 24 VDC power
supplies, five digital inputs and four digital outputs,
and RS-485 serial communications, making it an
excellent addition to any system.

SafeTouch Buttons
To make it possible to program and operate the
ProtEX-MAX in a hazardous area, the programming
buttons that are located behind the glass window can
be operated without removing the cover by using the
SafeTouch through-glass buttons. The operator puts
their finger on the glass over the button and the
button is actuated.
