MP SERIES STATIONARY INSTRUMENTS
MP202 & MP204 WALL-MOUNTED

The MP202 and MP204 are wall-mounted, microprocessor-based control units housed in weatherproof enclosures. The MP202 is a two-channel controller which can be used for 1 or 2 sensor channels, while the MP204 is a four channel controller which can be used for up to 4 sensor channels. A front door keypad enables convenient operation of the controller without the need to open the enclosure. 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. Both the MP202 and MP204 can be used with either our standard sensor transmitter (SM95) or our intelligent sensor transmitter (4-20IQ).

MP24 RACK/PANEL MOUNTED

The MP24 is a rack/panel-mounted version of the MP202. It is a compact control unit which accepts 1 or 2 sensor channels. Up to 12 of these control units will fit into a standard 19" rack or panel space, for a total of 24 sensor channels. Standard features include: 3 alarm setpoints per channel, digital display per channel, choice of individual or common relays, and choice of operating voltages (110/220 VAC or +24VDC). The MP24 can be used with either our standard sensor transmitter (SM95) or our intelligent sensor transmitter (4-20IQ). Please see below for details.

MP220EX EXPLOSION-PROOF

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.

The model 4-20 IQ is a microprocessor based intelligent sensor transmitter. It comes equipped with a digital display which provides a local reading of the gas concentration. Operating on 14-24 VDC power, it provides a linear 4-20 mA output proportional to the gas concentration, and is housed in an explosion-proof casing. The 4-20 IQ has been UL Classified and CSA Approved Class I, Div. 1, Groups B, C, and D. The 4-20 IQ can operate as a stand-alone instrument, or it can be used with an IST control unit to provide control room readings and alarm relays.

The 4-20 IQ come equipped with an automated calibration feature which allows the unit to be calibrated without manually adjusting any potentiometers. Just apply gas and the 4-20 IQ will do the rest. It couldn't be easier! Interfacing with the 4-20 IQ is accomplished by using a magnetic wand to activate magnetic switches located on the front panel. Thus, all functions can be performed with removing any covers, meaning there's no need to declassify an area being monitored. The 4-20 IQ can be used with any of IST's sensor technologies: infra-red (IR), solid state, catalytic bead, or electrochemical.

The model SM95 sensor transmitter is housed in an explosion-proof casing and operates on 14-24 VDC power. The SM95 has been UL Classified and CSA Approved Class I, Div. 1, Groups B, C, and D. The SM95 provides a 4-20 mA linear output proportional to the gas concentration and is calibrated by adjusting potentiomenters located inside the housing. The SM95 can operate as a stand-alone instrument, or it can be used in conjunction with any of IST's complete line of control units which provide control room readings and alarm relays. When used with any of IST's MP Series control units, automated calibration is provided, enabling calibration without the need to adjust potentiometers. Like the 4-20 IQ, the SM95 can be used with any of IST's sensor technologies: infra-red (IR), solid state, catalytic bead, or electrochemical.
