The BCP-8S has multiple operating modes that satisfy most steam systems. It can sequence stages to achieve an adjustable Set Point. Moreover, when used with the 420MOD Interface (389-900-226) it can accept a 4-20mA signal as a set point. The 420MOD must be purchased separately. This gives the BCP-8S the capability of being controlled remotely.
