I need a paperless recorder that can record Instruments analog signals (4 to 20mA) and digital signals (from field to DCS and vice versa) with a very short sampling time (1ms or less) so that we have first out alarm in equipment trips scenarios. We prefer this recorder to have clamp pins so that we can connect around the wires which are already connected to DCS and do not affect the process by removing these wires.
The objective is that we need to put a trap for the suspected trip signals for equipments such as pumps or compressors that sometimes trips with many signals come to DCS at same time and we can not identify what happened first as we do not have the fist out alarm facility on our DCS. It is preferred to be portable compact size so that we can take it to any system. Can any one help??
