*1 Stability output is only provided by the PS-T1 (P). Stability output for the PS-T2 (P)/T0 is sent from the PS-T1, FS-T1, FS-M1 or FS-R0.
*2 When several units are connected, the ambient temperature requirement varies depending on the total number of units connected.
When 3 to 10 units: -10 to +50 °C 14 to 122 °F
When 11 to 16 units: -10 to +45 °C 14 to 113 °F
When connecting several units, be sure to mount the units to a metallic DIN rail. Make sure that the output current does not exceed 20 mA.
