Po wer A 24 VAC, 50-60 Hz, minimum 20 VA trans forme r is ne cessary to
powe r a s ingle AXM board. Trans forme r s haring is allowed for
powe ring multiple AXMs . Binary outputs are powe re d through
se parate te rminals but may s hare the AXM controlle r’s
transformer. If s hare d, the VA rating of the controlle r’s trans forme r
must be increas e d to account for the additional load from the
binary outputs. See “Single -point grounding” on page 25.
Fus e Ale rto n Part Numbe r: BT-2.0A-5X20
Type : Onboard 2 Amp GDB fas t-acting fus e (5mm X 20mm)
Inputs Jumpe r-sele ctable , 12-bit unive rs al inputs acce pt following input
signals:
• The rmistor (3K or 10K ohm) or othe r re sis tive inputs (s oftware
scalable)
• Dry contact
• 4–20 mA (no e xte rnal resis tor re quire d)
•0–5VDC
• 0–10 VDC
Up to 100Hz puls e inputs are supported ONLY on inputs 1, 2, and
3.
Binary o utputs Binary outputs rated 24 VAC @ 0.5 A. Each binary output has a
Hand-Off-Auto (H-O-A) s witch for manual override of programme d
command. Us e one or more is olate d trans forme rs to powe r BOs
se parately from the AXM board s upply powe r.
Analo g outputs Analog outputs are drive n by a pre cis ion D/A conve rte r and are
DIP-s witch configurable to provide e ithe r 0–10 VDC or 0–20 mA.
Each analog output has a Hand-Off-Auto s witch for manual
ove rride of programme d command. Analog outputs als o include a
pote ntiome te r for manually adjus ting the output in Hand mode .
