The 
                    MP220EX is a two channel, explosion-proof, wall mounted, control 
                    unit rated for use in Class 1, Div. 1, Groups C & D (B 
                    optional) hazardous areas. Operation via magnetic wand allows 
                    the unit to be operated without opening the cover, thereby 
                    ensuring that hazardous areas do not require declassification. 
                    Standard features include: 3 alarm setpoints per channel, 
                    digital display per channel, common relays (optional individual 
                    relays), operates on 110/220 VAC (autoswitching), and 24 VDC 
                    power supply to power sensor transmitters. The MP220EX can 
                    be used with either our standard sensor transmitter (SM95) 
                    or our intelligent sensor transmitter (4-20IQ). Please see 
                    below for details.
