PD8-6310-WM ProtEX-MAX Explosion-Proof Weights & Measures Approved Batch Controller

The PD8-6310-WM ProtEX-MAX is an explosion-proof, NTEP® Certified pulse input batch controller certified as a weighing and measuring device that provides simple independent batch control operations where local control is preferred to expensive 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 field-mountable, NEMA 4X/IP68 rated enclosure available in either aluminum or stainless steel for convenient indoor and outdoor installation.

The controller has a mechanically secured programming lockout feature. A cable with compression seal may be secured to prevent the removal of the rear case, preventing access to the programming lockout jumper.

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 up to four 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 pulse (e.g. ±40 mV to ±8 V), square wave (0-5 V, 0-12 V, or 0-24 V), open collector, NPN, PNP, TTL or switch contact signals.

The PD8-6310-WM 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.
