EC8513
Incremental Encoder Counter
IndustryPack®
The Newwood Solutions IP-EC-8513 is a single-width Industry Pack that caters for four quadrature output incremental encoders. The signals Phase A, Phase B and Index from each of the four encoders are connected as TTL inputs at the I/O connector and operate on four 32 bit up/down counters which can be read or overwritten at any time. The maximum counting rate is 10MHz.
A companion unit, the 8906 DIN-rail mounted interface block can be used with this IP card (together with a suitable transition board) to provide RS-422 conversion for the encoder signals which then connect through individual D-type connectors to the plant.
An EPICs driver is available for this card.
The 8513 is a firmware variant of the IP-SC-8512 and has the following features :-
• 4 independent preset up/down counters.
• Full 32 bits binary count capacity.
• Each counter channel can count up/down from a pre loaded value.
• Count rates from D.C. to 10MHz.
• An ARM register allows individual channels to be enabled or inhibited.
• Maskable interrupt generated by each channel on encoder index pulse.
• Counter external inputs via transition board.
• Counters can be read on the fly via a shadow register.
• The ability to read the module identity, manufacturer, model, revisions and serial number from an onboard ID ROM.
